How many weeks of nausea did you experience?

I see a lot of women posting that their morning sickness is easing up after just a couple of weeks, but I can't find any medical literature about how common or normal that is online (and those of us that experience it get scared when the nausea goes away so soon when we expected to stay sick until 12 weeks at least!) I'm hoping this poll will help me see how common it is. I'm 8 weeks and my nausea is almost gone, it seems. Other symptoms persist.
